We look at the division of 450525 by 7 
Our goal is to divide 450525 by 7.

Going ahead to step 1:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 7

Step 2:
7 goes into 45 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 42 away from 45, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 7

Advancing to step 3:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 28 from 30, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 7

Going ahead to step 4:
When dividing 25 by 7, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 643.0
Subtracting 21 from 25 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 7

On to step 5:
7 can be fit into 42 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6436.0
If we take 42 away from 42, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 7

Going ahead to step 6:
When dividing 5 by 7, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 64360.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 64360.7
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 64360.71
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 64360.714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 64360.7142
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 64360.71428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 64360.714285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 64360.7142857
If we take 49 away from 50, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 64360.71428571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 64360.71428571, and the remainder is 3e-09.
